This is a prospective, observational, exposure-registration and follow-up study of women and their offspring exposed to Keppra (levetiracetam) and other UCB antiepileptic drugs (AED) at the time of conception (i.e., any time from the first day of the last menstrual period) and/or during pregnancy. The UCB AED Pregnancy Registry is designed to monitor pregnancies exposed to Keppra and other UCB AEDs in order to determine if there is a potential increase in the risk of major birth defects compared to rates from women in the general US population.

The objectives of the UCB AED Pregnancy Registry are:

• To prospectively collect data concerning 1) exposure to Keppra and other UCB AEDs during pregnancy, 2) potential confounding factors, 3) outcome of pregnancy, and 4) long-term pediatric outcome
• To review reported cases of possible birth defects
• To estimate the risk of birth defects occurring in live-born offspring of women exposed to Keppra and other UCB AEDs during pregnancy

This study is being conducted in the United States (US). Enrollment in the Registry is voluntary. The UCB AED Pregnancy Registry is sponsored by UCB, Inc. and is managed by Kendle International, Inc. The scientific conduct and analysis of the Registry is overseen by an Expert Panel consisting of external specialists in teratology/genetics, epidemiology, maternal and fetal medicine, and neurology (external member details available upon request).
